Features
- 16 channels + 1 Tref channel adapter for A5203/DT5203
- LEMO connectors
- Dual threshold discriminators
- Analog/NIM/TTL input signals
- Ideal to test the timing performances of A5203/DT5203 using signals from real detectors
- Possibility to correct for walk effect
Overview
The CAEN Mod.A5256 is a 16+1 channels adapter for A5203/DT5203 board. It provides dual threshold, leading edge discriminators for analog single-ended signals on LEMO coaxial connectors. It includes ultra-fast comparators with programmable thresholds (DAC) and accepts both positive and negative analog pulses, as well as NIM/TTL logic signals. It features a dedicated connector for Channel 0 to be used as a common time reference (Tref). The dual threshold allows for a better ToT to amplitude conversion and walk correction, as well as pulse shape discrimination.
